Application filed July 8, 1911. Serial No. 637,450.

To all whom it may concern:

Be it known that I, CHARLES J. OHLssoN, of the city of New York, borough of Brooklyn, Kings county, in the State of New ofork, have invente-d certain new and useful lmprovements in VehiclerWheels, of which the following is a full, clear, and exact speciication.

My invention relates to improvements in vehicle tires and the saine has fory its object more particularly to provide a simple, etlicientand reliable tire composed of a plurality of sections which may be readily assembled and secured in position upon a wheel rim.

, Further, said invention has for its object i to provide a resilient tire for wheels which tire is composed o't a plurality of sections each of which is independently adjustable.

Further, said invention has for its object to provide a tire for wheels which is so constructed andai-ranged that the outer or tread portion may be readilyadjusted in order to make the 'same concentric with the wheel rim.

Further, said invention has for its object to provide a tire for vehicle wheels, composed of a plurality of sections conforming to eachother and arranged concentrically with the wheehriin, and maintained yieldingl" in position thereon, and all of said sections secured in place by Ameans of a single, flexible member embracing all of said tread sections.

Further, said invention has for its object to provide a yielding or resilient tire in which the degree of resiliency may be readily adjusted to suit the particular condi- 4 tions under which the vehicle wheel iste be used.

To the attainment of the foregoingl objects e novel tion, connection and arrangement of parte, hereinafter more fully described and then pointed out in the claims.

In the accompanying-drawn forming part of this specification, wherein like numerals of reference indicate like parte, Figure 1 is a side view parti broken away, showing a portion oit e whee constructed according to, and embodying, my said invention; Fig.

2 is an enlarged transverse section taken on the line 2 2 of Fig, 1; Fig. 3 is an enlarged transverse section taken on the line 3--3 of Fig. 1, showing one of the supports und a tire section secured in position thereon; Fig. 4 is an enlarged detail plan view showing one othe tire sections'and the su port therefor, and IFig. 5 is an enlarged etail section taken on the line 5 5 of Fig. 1 illustrating one end of one of the semicircular plates upon which the spring sockets are mounted. l

In said drawings 10 designates e wheel comprising a hub 11, spokes 12, and rim 18. Upon the outer side of therm 13 is mounted an annular plate let composed of two semicircular sections 15, 15, each of which is broader than the rim-13. The opposin ende of the plate sections 15, 15 are provid inwardly extending ears or lugs 15, 15,

with

which are llocated at opposite sides of the,

diameter than the wheel rim 13, which sur-- rounds the same. The said annular member 18 is composed of a series of independent or separate tire supports each of which consists of avsegmental plate 19 having dependin anges or rims 192, 19 along its longitu inal edges, and a central, longitudinal recess 20 in its` outer side whose ends register with the endsl of similar recesses provided in the adjoinincr segmental plates 19, 19 in order that the same shall-)ointly form an annular groove.

Within each support or segmental plate 19 is secured a resilient tire section 21, which is referably made of rubber and has embedded) therein n lurality of bolts 22, 22 having comparativey large heads 23, 23

thereon in order to secure said bolts more 2G, 26 denote socket members 4having 'p04 lygonal heads and threaded stems 26, 26, adaptcdto be iittedinto threaded apertures providedin` the laterally projecting edges .of the semi-circular plate sections 15, 15. The threaded stems 26, 26 are provided with lock nuts 27, 27 whereby said socket members may be readily secured `to their adjusted positions.

28, 28 denote coil springs which serve to maintain the outer annular member 18 yieldingly in position surrounding the wheel rim, but free therefrom. The said springs 2S, 28 have their innerends located Within the adjustable socket members 26, 26, and their outer ends embracing the studs v25, arranged upon the segmental plates vThe tire sections are maintained duly in position, in end to end relation, and sur- Vinthe segmental plate 19, 19.

To assemble the tire, thesemi-circular plates 15, 15 with the socketmember 26, 2Q thereon are lirst secured to the Wheel rim 13. l-lereupon the segmental plates 19, 19, With their springs` 28, 28, are adjusted, and the parte then secured together by ymeans of the chain or flexible securing member 29. VAfter this has been done, the tire sections 21,' 21 are bolted in place upon ltheir respective seg-. mental plates 19, 19. Hereuponthe outer annular member 18 is trued up, or made concentric with the wheel rim 13 by adjustinoj the socket members 26, 2G as required. ll'ben ilie required adjustment has been obtained the socket members are secured to `their adjusted positions by means of the lock nuts 27, 27.

,it is to be not-ed that by means of m invention, il am enabled to produce a resi ieiit tire vwhich may be applied to a Wheel rim. and in which the degree of resiliency ma y be conveniently controlled by adjusting the socket members 26 26 and thereby 'varyinw having their ends located' within the socket members on said plate sections, and the re- 'i taining members on .said supports, tire sec-` l tions mounted upon said supports, and an annular .dexible member composed of a sei ries of similarly-shaped elements embracing said supports for maintaining the same in position surrounding said rim, substantially as specified. l

2. A .vehicle Wheel having a rim, a plate composed of two semifcircular sections, each broader than said rim and secured thereto,

sui orts tire sections mounted u on saidV supports, and an annular liexible member composed of a series of loosely connected link members arranged intermediate said supports and said tire sections for maintaining the same-in vposition surrounding said rim, substantially as specified.

3. A1 vehicle Wheel having a rim, a plate composedof two semicircularsections each broader than said rim means for securing said pla-te sections in position upon said rim, socket members` adjustably mounted,` adjacent to the edges of said plate'sectlon at both sides or' said rim, means for securing said socket members in their adjusted positions Aupon said plate sections, an annular member of greaterdiameter than Said rim comprising a series of separate supports arranged in end to end relation, and each having a longitudinal recess arranged thereinv projections on said supports, sprin having their ends disposed Within the soc tet members on said plate sections, and the projections on said supports` tire sections secured to said supports, and a flexible annular retaining member composed of a series of similarly-shaped link members located within the recessed portion of said supports. for maintaining the same in, pbsiilion and surrounding said rim, substantially as speclied. f Y

4. A vehicle Wheel having a rim, a plate composed of tivo se1ni.-circu ar sections each broader than said rim, means for securing Said plate sections io said socket members, threaded stems on said socket members eatending through `the laterally 'projecting edges ofV said plate sections, lock nuts an ranged upon said threaded stems, an annular member surrounding seid rim comprising a series of supports arranged in end to end relation, and each having a longitudinal .recess in its inner side registerino' with tbe longitudinal recesses in the adjoining 'up ports, studs arranged upon said supports vregistering with the socket members on said `plateY sections, coil springs having their ends Signed at the cit of New Yorkz in the disposed Within said socket members and county and State o New York, this third upon said studs, tire sections secured to said day of July, nineteen hundred and eleven. supports, and a chain havin I its ends se- CHARLES J. OHLSSON.- cured together and located wit in the annular recesses formed by the recesses arran ed in said supports, substantially as specie Witnesses:
